This is my second time doing a pork butt on my pellet grill and this time I bought the shoulder at costco thinking I was buying a 9.39lb single mass but it turns out that it's 2 separate pieces and both are deeply scored almost butterflied. How would I go about cooking this, do I need to tie it all up together or just keep them seperate? I already started the dry brine and want to start the cook around 5 am tonight.
